nah I think dart has fallen into the usual love affair that occurs with various schools after passing, I presume it's Alex's customer care which causes most of it. There really isn't much difference in the quality of the notes these days and most schools will do the job. The days of everyone wanting the 100 sheets of feedback questions from OAT are gone.
Personally I went to OAT DL and payed my money and got the job done with minimum fuss. And in those days there was a distinct advantage in going to OAT due to the cadets being organised to collect feedback. The volume of feedback was miles ahead of anyone else's. In fact their was a black market in feedback questions from OAT. I still think it has an advantage in this area.
Just to make sure though. Understand that nobody gives a toss about where and how you completed your theory exams or for that matter what mark you got for them. Passing with a 76% average or a 98% average is purely a personal self satisfaction pat on the back.
